UCC

This workload (test_template_name is UCCTest) allows users to execute UCC benchmarks within the CloudAI framework.

Test TOML example:

            

            
name = "ucc"
description = "Example UCC test"
test_template_name = "UCCTest"

[cmd_args]
docker_image_url = "nvcr.io#nvidia/pytorch:25.06-py3"
        

Test Scenario example:

            

            
name = "ucc-test"

[[Tests]]
id = "ucc.1"
num_nodes = 1
time_limit = "00:02:00"

test_name = "ucc"
        

Test-in-Scenario example:

            

            
name = "ucc-test"

[[Tests]]
id = "ucc.1"
num_nodes = 1
time_limit = "00:02:00"

name = "ucc"
description = "Example UCC test"
test_template_name = "UCCTest"

[Tests.cmd_args]
docker_image_url = "nvcr.io#nvidia/pytorch:25.06-py3"
